电计波描记器是在 X 线透视下,描记心脏边缘运动状态的电子仪器。应用 X 线记录心脏边缘运动状态的方法,目前有两种:即 X 线计波摄影(Roent-gen Kymography)及电计波描记(Electro-Kymography)。X 线计波摄影所记录的心脏运动波形(图1a)因受摄影装置的限制,不易观察细微的改变。而电计波描记之曲线图(图1b)则可清楚观察到0.1秒以上时间的瞬间微细变化。因此,电计波对某些心脏病有着特殊的诊断价值。 Electronic pedometer is in the X-ray fluoroscopy, tracing the edge of the heart movement of electronic instruments. Currently, there are two methods of recording the movement state of the edge of the heart using X-ray: Roent-gen Kymography and Electro-Kymography. X-ray wave recording of the recorded heart motion waveform (Figure 1a) due to the limitations of the imaging device, not easy to observe subtle changes. The plots of electromicrographs (Figure 1b) clearly show minute changes at moments of 0.1 second or longer. Therefore, the power meter for some heart disease has a special diagnostic value.
